Something doesn’t add up here. How about we keep the thread clean of all kinds of unnecessary speculation, especially when there is no news or facts on the basis of which this is being presented? No offence…

If the link is difficult to provide, could you at least mention the source? After all, a statement is just something someone says. I also just found a statement that “Putin, Trump, and Cristiano Ronaldo were in a sauna in Levi yesterday, but the heater wasn’t a Harvia.”
If the source is AI, it’s perfectly acceptable to say so. People’s curiosity has been piqued, though.

At least for me, Gemini doesn’t find any of the information you claimed (touchscreens, lidar heaters, etc.). Additionally, the links you posted don’t work.
This smells like a scam (Monday pump & dump) or an attempt to vaguely link Canatu to an obscure company.

I haven’t found any information about a partnership myself either, but the thought has certainly crossed my mind.
Apparently, a battery can function completely without carbon nanotubes, but with the specs promised by Donut Lab, it is very unlikely without some kind of CNT or similar nanostructure. Without them, charging speed, safety, battery life, etc. would be hard to achieve.
Let’s see.. Without Siilasmaa’s presence, I wouldn’t believe in Donut at all based on this information. There must be some truth to Donut’s claims. Wouldn’t Siilasmaa have surely distanced himself from Donut’s claims quickly if they weren’t true?

Siilasmaa has also invested in Canatu and probably many other places too.. heard it on a podcast. Trust me bro.

Those LUT supercapacitors are CNT/cellulose hybrids. In them, the CNT is mixed in, and is not a thin film. So, “bulk” CNT is bought cheaply and then made into a super-composite. Carbon nanotube supercellulose supercapacitor | IEEE Conference Publication | IEEE Xplore
I would give a 1% probability to a collaboration between Canatu and the super battery. The cost perspective must also be taken into account with batteries.

Here are some quick notes for those in a hurry, based on how I understood the matter myself.
In principle, that “technology testing / hundreds of wafers per day” would fit either FST/Samsung pre-production or TSMC’s FAT/SAT tests. At least TSMC will likely use standard EUV equipment in the 1.4nm node (2028), and there is a realistic possibility that testing is currently underway. It could, of course, also be Intel regarding their A14 node… My bet is on TSMC.
For me at least, that interview confirmed once again that we are following the right tracks in the media. Thanks to Atte for making the interview happen.

TSMC reported earnings today that exceeded forecasts for both results and outlook (guidance).
A couple of highlights regarding the future outlook:

It is also noteworthy that TSMC has moved forward the start of its new (No. 2) Arizona fab from 2028 to H2 2027. And construction of the third fab has also now begun. A fourth one is coming there as well.
Also as a side note: In yesterday’s discussion on geopolitics on Yle’s A-talk, Asia expert Teppo Turkki pointed out that China does not want to cause chaos in the global markets by attacking Taiwan.

The movement of blocks could be a sign of budding international interest, or it might not be.
Regarding Samsung, there’s some chatter about whether HBM4 memory chip production will start as planned in February or slip into Q2. Personally, I think this is the memory chip where Canatu will make its debut.
It’s worth asking Gemini (with a grain of salt) about upcoming production and manufacturing volumes for HBM4 and HBM4E, for example. Gemini mentioned, among other things, that in HBM4, the manufacturing of the DRAM layer will switch from old technology to EUV lithography. The targets for the memory (customers) are in the screenshots below.
According to Gemini’s claims, the HBM4E update coming in 2027 would already transition to High NA EUV lithography. In that sense, it would be logical to start gaining experience with Canatu’s pellicles right now.
Gemini can also tell/hallucinate how much Samsung has planned for this year’s HBM4 production. In a year’s time, in the financial statements, one could get a “royalties per wafer” estimate by using some estimate from here as a divisor, once we know how many reactors FST/Samsung are using to pump out wafers.
Interesting.

I’ve been thinking about Canatu for a while and tried to organize my thoughts into a single deep dive. It’s meant to be more conceptual than technical, even where I try to model future pellicle demand in semiconductors toward 2030.
That part in particular might be interesting if you’re thinking about a long term investment.
I could be wrong on many assumptions, but I do believe Canatu has the potential to be much more important over time than the market currently reflects.

This is playing right into Canatu’s hands.
Samsung Introduces ‘EUV Pellicle’ First in US Taylor Fab… Mass Production Imminent
Samsung Electronics will first introduce the key component ‘Extreme Ultraviolet (EUV) Pellicle’ to enhance productivity in advanced semiconductor processes at its Taylor fab under construction in the US. Although its adoption had been unclear until now, the company has essentially confirmed it by placing orders for key equipment.
According to industry sources on the 22nd, Samsung Electronics has ordered EUV pellicle facilities for its Taylor fab in Texas, USA. FST has secured a contract worth 25 billion won to supply EUV pellicle attachment/detachment equipment and inspection equipment.
The EUV pellicle is an ultra-thin protective component mounted on the photomask during the exposure process. Semiconductors are created by shining light onto a photomask with pre-drawn circuits to transfer them onto the wafer. Applying the EUV pellicle prevents fine particles or contaminants from adhering to the photomask surface, thereby mitigating yield reductions.
To use the EUV pellicle in exposure equipment, dedicated tools for attachment/detachment and inspection equipment to check its condition are required, and these will be introduced to the Taylor fab for the first time. The FST equipment supports not only next-generation carbon nanotube (CNT) EUV pellicles but also existing metal silicide (MeSi) EUV pellicles.
Previously, competitor TSMC has been gradually introducing Mitsui Chemicals’ metal silicide EUV pellicle since 2019 and applying it to advanced processes.
Samsung Electronics has been pushing for the localization of EUV pellicles by investing in S&STech and FST in 2020 and 2021, respectively. With this latest equipment investment, it is analyzed that sufficient performance has been achieved, signaling that adoption is imminent. This implies that the pellicle’s key performance metrics—durability and transmittance—have reached satisfactory levels.
An industry official stated, “The quality evaluation of the EUV pellicle is currently ongoing, but the introduction of equipment premised on mass production application at the Taylor fab is a positive development,” adding, “It is expected to expand to memory processes in the future, starting with system semiconductor processes.” The Taylor fab is a semiconductor manufacturing facility that Samsung Electronics is building with the goal of commencing 2-nanometer (nm) mass production in the second half of this year. Tesla’s artificial intelligence (AI) chip ‘AI5’ is also slated for mass production there within the year.
Samsung Electronics currently possesses over 70 EUV machines, ranking second after TSMC. As such, the adoption of domestically produced EUV pellicles is expected to have a substantial ripple effect on the equipment and components industry. The price of an EUV pellicle is estimated to be over 60 million won.
If I understood correctly:
- EUV lithography is in use in the production of the latest memories (as I speculated in my previous post)
- Mass production is starting (in my opinion, this still refers to HBM4 or similar memories)
- Samsung is introducing the use of pellicles as part of production at US fabs during H2.
- Assuming that the current ‘hundreds of wafers per day at a certain location’ is likely pre-production at some existing fab (e.g., Korea), then this news would suggest expanding the technology to the US side as well. This involves some uncertainty, but interpreting this through “Finnish lenses”…
- in any case, this increases the certainty of Canatu’s products being used in one or more fabs already this year.

Thanks to everyone who has written in the thread; you have greatly increased my understanding of Canatu.
Management has bought small amounts in early September 2025, but in my opinion, management’s holdings vs. the “winning” concept story do not go hand in hand.
Can anyone tell me something concrete about, for example, the expertise of the CEO or other leadership figures?
To me, the CEO’s speeches sound a lot like AI jargon, and they are leaning heavily on the success stories of AI winners.
Interesting company and product. I am considering investing in the company, but I think the current valuation is too high, and I would like to have a discussion about the expertise of Canatu’s management (one of WB’s evaluation criteria is the company’s management).

These key personnel have a whole slew of options, incentive schemes, and warrants that don’t show up in those direct holdings.
In these, the mechanism is usually such that they stand to benefit if the company’s value climbs to certain levels, which would encourage increasing the company’s value (I believe the options had triggers at the €14 and €18 share price levels). Then there are also those B-series shares with similar types of mechanisms.
I’m no expert in these and I don’t know management’s motives, but maybe if you’re already sitting on a stack like this (Kokkonen seemed to have over half a million options), you might not feel much of a need to buy shares directly from the market.
But one should be prepared for the fact that if things start working properly, there will be dilution ahead (someone more savvy than me had probably calculated these more precisely before).
